Audio write error when sending packets through KISS serial port

[antserrano]

I'm trying to send packets with Direwolf and a KISS application but I get the following error:

Audio write error: File descriptor in bad state

This is what I got at the beginning:

Audio input device for receive: dsnoop:1,0 (channels 0 & 1)
Audio out device for transmit: dmix:1,0 (channels 0 & 1)
Asked for 44100 samples/sec but got 48000.
for dsnoop:1,0 input.
Channel 0: 1200 baud, AFSK 1200 & 2200 Hz, E+, 48000 sample rate.
Channel 1: 1200 baud, AFSK 1200 & 2200 Hz, E+, 48000 sample rate.
Note: PTT not configured for channel 0. (Ignore this if using VOX.)
Note: PTT not configured for channel 1. (Ignore this if using VOX.)
Ready to accept AGW client application 0 on port 8009 ...
Ready to accept KISS client application on port 8001 ...
Virtual KISS TNC is available on /dev/pts/3
Created symlink /tmp/kisstnc -> /dev/pts/3

The thing is that if I connect my radio to a Ubuntu laptop everything works, the problem comes when I connect the radio to a Debian computer, which might cause the problem.

Any idea?

Hello. This Github issue system is for reporting bugs or requesting feature enhancements. Please close this issue, join the Yahoo support group at direwolf_packet@yahoogroups.com, and re-ask your question there. Many helpful people will chime in but I bet if you look at the output of "dmesg" at the time of the issue, you'll see USB issues. Those can be caused by RFI, low-voltage, etc. Try running your radio in receive-only and see if things run longer. If they do, you have a good starting point to troubleshoot from.
